Weight loss and AC impedance techniques were coupled with Scanning Electron Microscopy (AERST) and X-Ray Photoelectron Spectroscopy (XPS) analyses to characterize the inhibitive properties of AERST and to determine the chemical composition of the inhibitive film formed on the steel surface. AERST inhibited the corrosion of carbon steel in 1 M HCl, and its inhibition efficiency increased with the inhibitor concentration. However, a maximum inhibition efficiency of 83% was reached with 400 mg/L of AERST at 30°C. Adsorption of AERST on the steel surface in 1 M HCl solution followed Langmuir’s isotherm. The XPS studies showed that the inhibitive layer is composed of an iron oxide/hydroxide mixture where AERST molecules are incorporated.Lire moins >
